[Pharo-project] Cog-Win32 build on Jenkins
by Martin Sandiford March 26, 2012

March 26, 2012

Hi All, Any chance that the "Cog-Win32" Jenkins job could be made dependent on the "Cog Git Tracker (blessed)" job in the same way as the Mac and Linux VMs are? I ask because I see that the job hasn't been built after the last couple of changes to the blessed repo. Cheers, Martin

[Pharo-project] GSoC more mentors wanted
by Janko MivÅ¡ek March 26, 2012

March 26, 2012

Dear Smalltalkers, We have quite nice projects, but mentors are still missing: http://gsoc2012.esug.org/projects http://gsoc2012.esug.org/mentors Note that current mentors are potential mentors and more project proposers than final mentors, so, if you are interested to mentor some project, contact the current mentor and volunteer to be a mentor, or second mentor, of that project. Same goes for current mentors, please be sure that your projects will have a proper mentor and second mentor. What's difference between mentor and second mentor? Mentor is responsible for a project and student through the whole project lifecycle, while second mentor is officially to replace the main mentor in a case he cannot be mentor for any reasons anymore, but unofficially second mentor also helps the main mentor working on the project. There is only one main and only one second mentor possible. So please, anyone interested please look at the projects and volunteer for membership. By replying to me or Carla, or to the current potential mentors. Best regards Janko -- Janko MivÅ¡ek Smalltalk GSoC Admin Team http://gsoc2012.esug.org

[Pharo-project] Seaside Book: Chapter 17, Serving Files
by Schwab,Wilhelm K March 26, 2012

March 26, 2012

Stef, Thanks for Dynamic Web Development With Seaside - it's a great book! One omission that I have noted is that of dynamically serving files. Making a long story short, I have a Seaside app that swallows and regurgitates literature (300 MB and growing). It is what has me interested in Citezen (which is working wonderfully - thanks again!). I wish I had known more about Seaside when I started to write it, but it is slowly improving. Clearly, I can't put hundreds of megabytes in a FileLibrary, and I have no interest in configuring a static web server for something that (sadly or not) runs locally on multiple machines, with data synchronized via what amounts to an rsynch clone and ever-growing flash sticks. The answer is to serve the content dynamically, as below. I think this technique deserves mention in Chapter 17. Bill serveFileNamed:fileName for:component canvas:html | mimeType | ( File splitExtensionFrom:fileName ) = 'pdf' ifTrue:[ mimeType := 'application/pdf' ]. ( File splitExtensionFrom:fileName ) = 'txt' ifTrue:[ mimeType := 'application/text' ]. ( File splitExtensionFrom:fileName ) = 'gz' ifTrue:[ mimeType := 'application/x-gzip' ]. component session requestContext respond:[ :response | response document:self fullTextAsString mimeType:mimeType fileName:fileName; doNotCache ]

[Pharo-project] FFI error message: Heisenbug
by Schwab,Wilhelm K March 25, 2012

March 25, 2012

I'm working on GSL+callbacks, and have hit a genuine Heisenbug - the behavior changes depending on when/where I break and/or step over or into code. Callbacks are getting hit successfully(!!!) but there is one function that crashes, unless I step over the call, in which case I get an error. In particular, if I step far enough into things to see the call, calling gsl_multifit_fdfsolver_set() is raising an error (vs. crashing if I don't look<g>) that says 'No module to load address from'. Anybody know what that means? I'm using the CogVM on Ubuntu Lucid. Bill

Hello I just created a configuration of the New ECompletion package. Now it worked nicely in 1.4. I hope one of these days to have the time to fix OCompletion to work nicely and without breaking ECompletion. Gofer new url: 'http://ss3.gemstone.com/ss/NEC'; package: 'ConfigurationOfNewECompletion'; load. ((Smalltalk at: #ConfigurationOfNewECompletion) project version: #stable) load Stef

[Pharo-project] Reducing the use of DependentFields
by StÃ©phane Ducasse March 25, 2012

March 25, 2012

Hi DependentFields is a classVar in Object to make sure that an object can have dependent even if it does not inherit from Model. Cuis got this fixed and I would like to get the same. Now finding users of it is difficult. I found that MCWorkingCopies use a lot this behavior but I'm looking where exactly. So may be changing the superclass of MCPckageManager is the solution. Any ideas? Stef

[Pharo-project] Weird change in Project class >> spawnNewProcess
by Martin Dias March 25, 2012

March 25, 2012

Hi Debugging a Fuel test case, I discovered something I can't explain myself: Project class>>#spawnNewProcess is replaced in the middle of the *first* test run, between serialization and materialization. This happens the *first time* I run the test in a *clean* Pharo 1.3 image, after first time, the method doesn't change anymore. In 1.4 we don't have to problem. I logged the method sources, and actually there is a difference: -- during serialization -- 'spawnNewProcess UIProcess := [[World doOneCycle. Processor yield. false] *whileFalse.* * nil*] newProcess priority: Processor userSchedulingPriority. UIProcess resume' -- during materialization -- 'spawnNewProcess UIProcess := [ [World doOneCycle. Processor yield. false] *whileFalse: [].* * *] newProcess priority: Processor userSchedulingPriority. UIProcess resume' -- system info -- Pharo1.3 - 13327 - 'Croquet Closure Cog VM [CoInterpreter VMMaker-oscog-EstebanLorenzano.139]' Do you know why this happens? Thanks, MartÃn

[Pharo-project] Building the iOS VM
by philippe.back＠highoctane.be March 25, 2012

March 25, 2012

I am trying to build the VM for iOS. Got the sources from the ci jenkins server (the ones that built last month, as the current one is red). /platforms has something looking like it. (iOS) But cog is x86 and iOS is ARM7. So, I guess that I have to build a StackVM for it to work. But there is nothing about iOS in the instructions (Part1, Part2, ...) The MacOSX VM is documented but not the iOS version. As maintenance was taken over from John, how do we build from here? My setup: OSX Lion, latest XCode upgraded from Snow Leopard, so I do have GCC on it as well (as LLVM doesn't work). Target devices: iPad 2 3G, iPad 2 Wifi, iPhone 3GS (All with iOS 5.1). My wife is a math teacher and my point with all this is to have a working VM running Dr Geo II. I am currently having fun with Arduino and would like to bridge it with the iPad through the web (using an Ethernet Shield on the Arduino) - the whole chain running Pharo inside self build VMs. The ultimate point is to run a summer camp with kids if I can put everything together by then. Thanks in advance, Philippe
